Be it known that I, OTTO THIEME, a cit-izen of the United States, residing at St. Louis,-Missouri, have invented a certain new and useful Improvement in Adjustable Paper-Guide 'Fingers for' Type-Writing Machines,o;f which the following is ,a"full, clear, and exact description, such'as will .enable others skilled in the art to whiehqit appertains to make anduse the same, reference being had to the accompanying drawings, forming part of this speciica'tiomfin Whch- "-1 '1 f Figure 1 is a plan view of one' form of my improved device as appliedto the platen of an ordinary typewriter.' Fig.- 2 is a side view of my device. Fig. 3 is an elevational view of amodied'form. .i

M1511 invention relates to an improvement in t e guide finger which is .employed on the usual form of typewriter to engage and hold the paper sheet around the platen.

1 lt is'desirable that such fingers be made of simple and cheap construction and ythat these fingers may be capable of adjustment on their supporting bar'.

My improved devicecomprises a finger i n l portion, which 1s of ordinary construction,

and a clamp portion for engaging the supportingbar. which is novel.

Referring to the drawings, the numeral 1 designates the platen of anordinary typewriter mounted' as usual on a traveling carriage.

2 is a supporting bar in front of the platen and suitably supported at each' end by the platen spindle 3. This bar 2 is preferably, although not necessarily, square in 'cross section with the `diagonale of the square in `vertical and horizontal position, respectively.

The guide finger as shown at Fig. 1 is comprised of a strip of resilient material having a guide finger portion 4- curved to embrace the periphery of the platen 1. This linger portion is Ybent aty v5-tcform a horizontal section and then rebent at 6 into a s ring loop or clamping portion 7. This c ampmg portion is notched at either side as indicated at Sand 9 b yfcrimping` the matferial t0 form clamping seats, which are to engage the opposite corners1 10 and 11 of the f supporting bar 2 as shown in Fig. 2. Above the inner notch 4it is another notch 8', in

which may be seatedthe projection or corner 10 when it is desired to retain the finger piece on the bar,V but with the guide portion 4 removed from the platen to allow of the insertion of several thicknesses of paper.

The endv of thestrip 12 is preferably turned outwardly in order that when the' clampingV loo is `passedover the bar 2 the l op 7 will springsuflieiently to-allo'w'the notchesv 8 and 9to engage the cBorners 1 0 and 11, respectively,` of the bar 2.

sired,` on the supportin bar 2, and may be any position desired. l,

In-Fig. 3. s shown `a sli ht modification in the form of the' finger, w ichnconsists not only of a strip passing vdownward from` the clamping `loop and around the platen,`

but also a lateral 5Wing13 v.extending from periphery of the;l platen.

I am aware thatminor' changes may be made in my construction, and in the comsection mounted on the carriage of the ma chine in front of the platen, of a paper o'uide comprisinga single integral member having an inverted U-shaped portion the lower. portions of the legs of which are adapted to engage an opposite pair of cor- 4ners of the square bar and a curved arm extending downwardly and forwardly from one of the legs, vwhich Aarm is adapted to bear against the platen.
